From the team behind the New York Times bestselling Creepy Carrots! and Creepy Pair of Underwear! comes the third in this hilariously spooky series about a young rabbit and his peculiar encounters--featuring a sinister crayon!

Jasper Rabbit has a problem: he is NOT doing well in school. His spelling tests? Disasters. His math quizzes? Frightening to behold. But one day, he finds a crayon lying in the gutter. Purple. Pointy. Perfect. Somehow...it looked happy to see him. And it wants to help.

At first, Jasper is excited. Everything is going great. His spelling is fantastic. His math is stupendous. And best of all, he doesn't have to do ANY work! But then the crayon starts acting weird. It's everywhere, and it wants to do everything. And Jasper must find a way to get rid of it before it takes over his life. The only problem? The creepy crayon will not leave.
